deadhorse << lets beat it. MY catch can setup.. am i getting it right?
so yes i searched. and searched and got answers. but not many matched. ive noticed there is no perfect way but the way that works best for you. i noticed most catch cans i read about were turbo applications. i am vorteched. so long story short after my last track day i had slight blow by coming from my driver side valve cover which i did not at the time have routed to my catch can.... after hours n hours of looking i thought i had it down. went with this setup..

car did not like this at all. idle was far to lean.
so i read more and got more confused. finally what i got from it all was vent the valve covers period. so this is what i did i drilled the pcv out routed that to the catch can also routed the drivers side valve cover to a T fitting w the pcv valve so they both enter the same side of the baffled catch can. the other end ive routed down under the car and and hidden towards the back of the car so the fuel vapors dont kill me in the car lol. and i capped off the intake manifold with a nipple plug. sooo basically they system would in theory be just like running breathers off both valve covers and plugging the intake manifold just with the can in the middle to help seperate the oil/etc. car runs n idles great...
so. does this make sense and will the system work properly. no check valves no ********. just venting both valve covers to atmosphere with a catch can in the middle.
i track the car often. and after all the fuel vapors i took in today trying diff setups i just want a lil forum soft n fuzzies. thanks n sorry for dragging on..

That will work fine. Nice and simple.
Just fyi, long runs of small hose add resistance to escaping vapors and still allow crankcase pressure to build under boost. I would recommend 5/8" hose for anything longer than a couple feet (not sure how far you routed hose down under the car). Most folks just have a breather filter right on the catch can. Depending on placement, that may allow fumes to enter the passenger compartment, so I understand trying to route under the car, but just keep in mind the drawback of long runs of hose.
